The hand harness is a device which shall be used to aid the hands in remaining closed around the boom of a sailboard or a land sailboard. This device works, by first very firmly attaching to the forearm a thick sleeve 12 that covers nearly the entire forearm. The inside of this part is to be made of 1/8 inch thick neoprene that is rubberized on the inside (or other comparable material). Across the top of the forearm is a thick nylon strap 7. In the middle of this thick strap is a loop into which the steel finger 3 is attached. The steel finger 3 starts as a rectanglar piece 8d that starts in the thick loop in the nylon strap on the middle of the top of the forearm. Finger 3 extends down the forearm and across the hand. From here it goes between (in a closed hand position) the first and second fingers (first being the index) and stops just past the point of contact on a firmly grasped boom 1. A chain, strap, or similar device 16 runs from an extension at the bend in the steel finger 3 and runs to spot 15 that is located at the extreme end of the webbing 14 that sits between the first two fingers. Its purpose is to clamp down the steel finger 3 when the hand is closed about boom 1.
